Relationship between landscape structure and avian abundance patterns in the Oregon Coast Range

Creator:

McGarigal, Kevin

Abstract:

Human-induced fragmentation of forests is increasing, yet the consequences of these landscape changes to vertebrate communities are poorly understood. Despite progress in our understanding of how bird communities respond to forest fragmentation caused by agricultural or urban development, we have little understanding of these dynamics in landscapes undergoing intensive forest...

Quantitative genetic structure of Douglas-fir populations from southwest Oregon

Creator:

Hamlin, James

Abstract:

The major objectives of this study were: (1) to determine the extent to which southwest Oregon populations of Douglas-fir [Pseudotsuga menziesii var menziesii (Mirb.) Franco) differ in quantitative genetic structure (QGS); (2) to determine whether differences in QGS are associated with the environments from which populations originate; and (3) to...

Spatial and temporal population dynamics of Cantharellus formosus, the Pacific Golden chanterelle, in Oregon

Creator:

Collins, Kelly Patrice

Abstract:

This dissertation was undertaken to improve the understanding of the population dynamics of the Pacific Golden chanterelle, Cantharellus formosus. It addresses the longevity of individuals over a 12 year period and the limits of gene flow within the area of a 6,400 hectare watershed at the H.J. Andrews Long Term...
